System Configuration with Central Powering of Remote Intercoms
Figure 5
Flowire Upgraded configuration with central power distribution.
In the figure above, there are two Flowire star configurations, each with one central FCDC2 Flowire
Converter and one central PSU (Power Supply Unit). FCDC1 is used to power the connected
device via the spare pairs of its Ethernet port There can be no cross connection between these star
configurations inside the main distribution frame.
The figure above shows how the Flowire upgraded system configuration will look when all remote IP
products are powered by centrally located PSUs.
L
Only use FCDC2 together with the central PSU in the main distribution frame.
L
All multi-pair cables for one Flowire star configuration has to be gathered in the central
FCDC2. This can be done directly in the FCDC2 if the plug has room for it, on connector rails
or by some other means.
L
You must never cross connect two Flowire star configurations.
L
You must never have wires from different Flowire star configurations share the same multi
-
pair cable as this will lead to a very detrimental form of crosstalk.
L
You must never ground any of the devices at the remote sites as this may draw additional
current from the central PSU to the remote sites, thus reducing the power distribution
performance.
